Using this compensation makes the OPA686 one of the premier 12- to 14-bit analog-to-digital converter input drivers.
The supply current for the OPA686 is precisely trimmed to 12.
4mA at +25°C.
This, along with carefully defined supply current tempcos in the input and output stages, combine to provide exceptional performance over the full specified temperature range.

The classical differential input stage, along with two stages of forward gain and a high power output stage, combine to make the OPA686 an exceptionally low distortion amplifier with excellent DC accuracy and output drive.
The voltage feedback architecture allows all standard op amp applications to be implemented with very high performance.
